2、Global Technologies, Inc. STEEL, STAINLESS (TITANIUM STABILIZED) MODIFIED ESA-M1A64-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a ferritic, corrosion resistant steel. It is non-hardening by heat treatment, thus enhancing weldability. The low rate of work ha

3、rdening coupled with good ductility promotes good forming properties. 2. APPLICATION This specification was released originally for material to be used for the manufacture of muffler and exhaust system components. 3. REQUIREMENTS Material specification requirements are to be used for initial qualifi

4、cation of materials. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 CHEMICAL COMPOSITION (Ladle Analysis) Carbon 0.08 max Chromium 10.50 - 12.50 Nickel 0.50 max

5、 Manganese 1.00 max Silicon 1.00 max Phosphorus 0.045 max Sulfur 0.045 max Titanium 6 times carbon min - 0.75 max 3.3 SURFACE FINISH Material supplied for the exhaust system components are to be annealed in deoxidizing (reducing or inert) environment. Other desired finishes are to be specified on en

6、gineering drawings. The surface shall be sufficiently free from scale and oxides to ensure suitability for blanking, deep-drawing and forming on high speed tube mills without causing excessive tool wear or breakage. Surface scratches, nicks and gouges are acceptable but shall be kept minimal. ENGINE

8、or high frequency processes to yield reasonably ductile weld joints. 3.6 BEND TEST The material shall not crack when subjected to the following tests: Test Method: Bend 25 mm x 200 mm sheared edge specimen 135 along the 25 mm dimension at the center of the specimen. Insert the bend specimen in a han

9、d vise, bend section in jaws of vise, and complete specimen bend to 180. Remove from vise and examine specimen along bend for evidence of cracks. 4.
